BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a gaseous fluid-operated ozone supply unit, and more particularly to an innovative one which enables to control ozone's opening and closing state through air-operated negative pressure.

2. Description of Related Art Including information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.

Ozone (molecular formula: O₃), an allotrope of oxygen (O₃) is able to eliminate instantly planktonic bacteria in the air, decompose toxic gas and remove foul smell, etc, so ozone is widely applied for purification of air, potable Water and sterilization, etc.

There are currently available with a variety of ozone generators, one of which is commonly incorporated onto an existing faucet for purification and sterilization of water supply as discussed in the present invention.

Some problems of a conventional ozone generator start-up structure are still observed in actual applications. For example, as the water flow-induced control structure of a conventional ozone generator is concerned, a reed switch is arranged generally in the water supply passage of the faucet. The water supply passage is internally equipped with a fixed magnet and a movable magnet, and externally provided with an induction switch contact. This structure is operated in such a way that the yielding water pressure pushes the movable magnet to shift towards the fixed magnet correspondingly to the induction switch contact. In such a case, the induction switch contact will be electrically connected due to magnetic force, then the ozone generator is activated. When the water supply is shut down, the movable magnet could be reset via the repellent action of magnetic pole of the fixed magnet, meanwhile the induction switch contact is in open circuit state, allowing to turn off the ozone generator. Yet, as the water flow-induced control structure of the ozone generator is arranged into the water supply passage, the flow rate and smoothness of the water supply passage will be highly affected, and the impurities and dirt in the stream likely lead to unsmooth operation or even locking of the movable magnet. Moreover, there is also a common concern as to whether the movable and fixed magnets in the stream results in water pollution.

Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved, structure that can significantly improve the efficacy.

Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.

BRIEF SUMMARY OF THE INVENTION

Based on the innovative design of the present invention wherein the “gaseous fluid-operated ozone supply unit” mainly comprises a housing, output duct, ozone generator, air induction member and controller, the drainage effect generated from water guide will discharge air in the output duct, so that the output duct could generate negative pressure state, enabling to control ozone's opening and closing state through air-operated negative pressure. As compared with prior art wherein the induction-operated control structure is arranged in the water supply passage, the present invention could maintain the flow rate and smoothness of the water supply passage, so as to remove impurities and dirt in water and prevent blocking or even disabling of active magnetic inductor for improved applicability and ease of operation.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1-5 depict preferred embodiments of a gaseous fluid-operated ozone supply unit of the present invention, which, however, are provided for only explanatory purpose for patent claims. Said gaseous fluid-operated ozone supply unit 05 includes a housing 10, designed to form a hollow holding space 11.

An air inlet portion 20 is set externally or internally on the housing 10, and used to guide external air (set externally on the housing in this preferred embodiment).

An ozone outlet 30 is set on the other location of the housing 10 for ozone output. The ozone outlet 30 is provided with a check valve 31 (only marked in FIG. 1) for irreversible output.

An output duct 40 comprises of a coupling end 41 and an extension end 42. The coupling end 41 is connected with the ozone outlet 30. The extension end 42 is extended to a preset target 06 for the ozone, and the preset target 06 must be capable of guiding the stream so that the output duct 40 could generate negative pressure.

An ozone generator 50 is set into the bolding space 11 of the housing 10 for generating ozone. The ozone generator 50 comprises of an air guiding portion 51, an ozone discharging portion 52 and an ozone generating portion 53 located between the air guiding portion 51 and ozone discharging portion 52. Of which, the ozone discharging portion 52 is connected with the ozone outlet 30.

An air induction member 60 is set between the air inlet portion 20 and ozone generator 50 and comprises of: a guiding pipe 61, set vertically, including a lower inlet end 611, an upper outlet end 612 and a guiding section 613 located between the upper outlet end 612 and lower inlet end 611. Of which, the upper outlet end 612 is connected with the air guiding portion S1 of the ozone generator 50 via a connecting tube 614, and the lower inlet end 611 is connected with the air inlet portion 20.

An active magnetic inductor 62 is arranged into the guiding section 613 of the guiding pipe 61 in a liftable state. A magnetic body 63 is set at one side of the active magnetic inductor 62, and the active magnetic inductor 62 is driven into a floating state when the output duct 40 is under negative pressure state. An induction circuit board 65 with Hall component 64 is set at one side of the guiding pipe 61. Said Hall component 64 is arranged at one side of the induction circuit board 65. When the active magnetic inductor 62 is in a floating state, the magnetic body 63 is aligned with the Hall component 64, such that said Hall component 64 could generate an induction signal.

A controller 70 is set into the holding space 11 of the housing 10 (indicated by FIG. 2), and electrically connected with the induction circuit board 65 and ozone generator 50, enabling startup of the ozone generating portion 53 of the ozone generator 50 when receiving the induction signal of the Hall component 64. Otherwise disabling the ozone generating portion 53 of the ozone generator 50 when the induction signal of the Hall component 64 is not received.

With this design, the present invention has provided an ozone supply unit which enables to control ozones opening and closing state through air-operated negative pressure.

Based upon above-specified structural design, the present invention is operated as follows:

Referring to FIGS. 1 and 3, a filter assembly 21 is arranged on the air inlet portion 20 of the housing 10, and preferably made of sponge.

Referring to FIG. 5, the cross section of the guiding section 613 of the guiding pipe 61 is set into rectangular, square, elongated and polygonal patterns. The cross section of the active magnetic inductor 62 is mated with that of the guiding section 613, so that lifting state of the active magnetic inductor 62 could be positioned securely and the magnetic body 63 on the active magnetic inductor 62 could be oriented normally towards the Hall component 64.

Referring to FIG. 7, the active magnetic inductor 62 is fitted with through-type ventilating portions 66, which are formed by penetrating the through-holes of the active magnetic inductor 62. Or, referring to FIG. 6, spaced ribs 80 are formed on the periphery of the active magnetic inductor 62, then said ventilating portions 66 are formed by the space between various spaced ribs 80. Moreover, the spaced ribs 80 come into contact with the guiding section 613 of the guiding pipe 61, thereby reducing the frictional resistance of the active magnetic inductor 62 in lifting state, and enabling more smooth lifting of the active magnetic inductor 62.

Referring also to FIG. 7, said active magnetic inductor 62 is designed into a columnar pattern viewed from its appearance.

Next, the working condition of the present invention is described below:

FIGS. 2-4 and 8 and 9 depict preferred embodiments of the present invention in service state, wherein the preset target 06 for the ozone is fitted with a mixer 12 at water outlet A1 of existing faucet A. The mixer 12 is a mixing element of water and air, which is connected with the extension end 42 of the output duct 40 of the ozone supply unit 05 disclosed in the present invention. Thus, when the user opens the faucet A to guide water from the water outlet A1 (shown by arrow L1 in FIG. 8), the mixer 12 could yield drainage effect to discharge air in the output duct 40 from the air guiding portion 51 of the ozone generator (shown by arrow L2 in FIG. 8), such that the output duct 40 generates a negative pressure state, and the active magnetic inductor 62 in the guiding section 613 of the guiding pipe 61 is driven into a floating state. Furthermore, the magnetic field generated by the magnetic body 63 (shown by arrow L3 in FIG. 8) could generate an induction signal together with the Hall component 64. When the controller 70 receives the induction signal of the Hall component 64, the ozone generating portion 53 of the ozone generator 50 is activated, so that the ozone generating portion 53 could generate ozone, which is discharged through the output duct 40 along with water (shown by arrow L4 in FIG. 8). To the contrary, when water flow stops, the negative pressure state could be removed and the active magnetic inductor 62 is reset; when the controller 70 fails to receive induction signal from the Hall component 64, the ozone generating portion 53 of the ozone generator 50 is disabled. With this structural design, it is possible to improve the shortcomings of prior art that the induction-operated control structure is arranged in the water supply passage, but often blocked or even disabled due to impurities and dirt in water.

Moreover, the preset target 06 for the ozone could also be assembled into a venturi at the water inlet of an existing faucet, then the drainage effect could be generated by the pressure difference from said venturi such that the output duct 40 could generate negative pressure similarly.
